Foundation pit underground water collecting structure and foundation pit bottom sealing construction method
The invention provides a foundation pit groundwater collecting structure which comprises a blind ditch and a dewatering well which are communicated with each other, a drainage pipe used for draining groundwater in the blind ditch to the dewatering well, and a permeable filling filter material filled in the blind ditch, the drainage pipe is embedded in the filling filter material, and the drainage pipe is communicated with the dewatering well. The space between a water outlet of the drainage pipe and the water filter pipe is filled with the filling filter material, a plurality of rows of water seepage holes distributed in a surrounding mode are formed in the drainage pipe, and every two adjacent rows of water seepage holes are alternately distributed in the axial direction of the drainage pipe. According to the technical scheme, underground water flowing into the dewatering well from the drainage pipe can be filtered, foreign matter impurities brought into the dewatering well are reduced, the influence of the foreign matter impurities on extraction and drainage is reduced, and the extraction quality and efficiency are improved.
本发明提供一种基坑地下水汇集结构，包括相互连通的盲沟和降水井、用于将盲沟中的地下水引流至降水井的排水管，所述降水井内设有滤水管，还包括填充在盲沟内的可透水的填充滤料，所述排水管埋设在填充滤料中，所述排水管的出水口与滤水管之间填充有所述填充滤料，所述排水管上设有若干排环绕排布的渗水孔，相邻两排所述渗水孔沿排水管的轴向交替布置，以及一种基坑封底施工方法，基于基坑地下水汇集结构的施工方法，本技术方案可实现对从排水管内流入降水井的地下水进行过滤，减少异物杂质被带入降水井，降低异物杂质对抽取排出的影响，提高抽取质量和效率。
